Gran Turismo 7’s New Physics Are Not Entirely Going Well

[hawkeyez]

I find most cars after that update were wallowy. Even my wide body pantera stock with wide tires and offset were rubbing the fenders. It never did that before.

 

[sonnyboychris]

it’s just too otherworldly for a simulator.

Well... That might be your problem right there. 🤣

Spoiler

I kid... I kid... Before some of you breakout the pitchforks.

Not really? Semi slicks, sure, but not full slicks. The SLS is a GT car, not a supercar IIRC.

Regardless wether the car is capable on slicks or not,this never happened prior to update 1.50.Same for the cars having issues since 1.50,we cant all be making it up.

 

[jrbabbitt]

To be fair, you can't just put slicks on a car with stock suspension or it will indeed do insane things like bottom the suspension out.

That and I bet that brake bias is all way fwd as the front tyres locked up very hard and fast....

I'm not sure folks are thinking that others are making up their experiences. I think there are some differences in the experiences that different folks are having, due to various reasons including different input devices, driving settings, car settings, and all sorts of other differences. If you don't often drive stock vehicles, particularly with sticky tyres, you might not have noticed these things. Conversely, if you regularly run older cars with wide wheels and racing tyres, or lowered suspensions, you may run into these types of things all the time. If you spend most of your time driving GT3s, you may think everyone is nuts anyway.

I suspect that most folks have experienced a car that bottoms out or has limited steering angle due to fender clearance, etc. I think the disagreements mostly lie in different opinions as to whether these things are realistic or not. And I don't think that we will find a consensus on that matter here. And even if there was a consensus on whether these changes are realistic or not, you will still find people who prefer the current or former update better. Just like some folks like iracing, and others call it iceracing. Some like ACC, and others find that game completely undriveable.

I get a lot of braking deviations on some cars that wouldn't before 1.49, specifically very strongly tuned cars and FR's and some MR's.

I hear what you are saying but these issues didnt seem to appear before the update.Stock cars with sticky tyres worked fine,as for the brake bias being all the way to the front,thats another one to add to the the list of reasons why these things happen.Cant possibly be issues with the physics though.

I do hope they fix the physics, it's getting really annoying trying to do hotlaps and this happens:

I really love the way the C2 Vette drives and how capable it is for its age, but the stickiest tire I've ever run on it is SH, and the rest of the car has remained stock. Putting slicks on street cars without tuning for them specifically will lead to trouble in game and IRL, but I 100% agree that this behavior is still absolutely ridiculous.

Ah, the infamous “driver error”.

What great fun that back and forth was. Nothing like showing someone rock-solid proof over and over again only for them to completely ignore it based on extreme inexperience and a complete inability to comprehend how a car is supposed to physically function. Had to throw up my hands and bounce out of that exchange. You and Nebuc were fighting the good fight... haha.

To be fair, you can't just put slicks on a car with stock suspension or it will indeed do insane things like bottom the suspension out.

It is true that running slicks on a car that isn't prepped for them is not a good idea, but bottoming the suspension out is not really one of the ways this bad behavior should manifest. It has more to do with the crazy increase in mechanical grip paired with soft suspension that can't respond to it safely. Insert uncatchable snap-oversteer here.

I've heard of cars in autocross literally rolling over while running slicks on stock suspension. Bottoming out/hitting the bumpstops is more a matter of compression due to elevation change, but the new soft suspension setups paired with a sticky tire the issues with bounce-back many of us have been experiencing in normal cornering are surely exacerbated. That said, this kind of thing happens on SH-SS tires too, like in the EVOs.

All in all, still lots of issues with the Michelin model, and I'm hoping that next weeks update has some physics changes in it as well.

Re: physics


Taking the cars out in race A of the dalies has led me to notice a little, low key, but very often subtle bouncing. First noticed it coming out of corners and thought it was my wheel unloading the weight kinda chunky and funny. Then i realized it was the car. Its barely noticeable in the replays, but there. Certainly not the end of the world..but not great. Hopefully, they take a swing with the patch at this stuff.

The one car that’s always got me right from day one, was the 1965 Shelby Mustang GT350. You widebody it. Put wide tires on and offset, it rubs, take the offset off, it hits, finally remove wide tires, it doesn’t hit but it looks ridiculous. What’s the point of doing widebody if you can’t put wide tires and offset on. Most of the time now, I just do wide tires only when I widebody a car so I don’t have to go back to GT Auto and remove offset because there’s a good chance it’ll hit. If we could change that in settings on track then at least we could throw both on, drive it, find it hits and remove one or the other.

I don’t know it just feels like if I brought my car in somewhere and said widebody it and give me fatty tires and some offset the shop would make sure the tires wouldn’t hit. GT7 is like it’s a gamble, the shop doesn’t check clearances and sends you on your way. Oh you didn’t want the tires to rub? Sorry we didn’t know that. Or, sorry it just doesn’t work on this car. Ummm ok thanks?

Alright. Some interesting things to note here.

Wobble1 in the camera settings is now far superior to wobble2. It's not even close. You get more exaggerated movement with wobble 2 but you get WAY more feedback with wobble 1 not to mention the camera and wheel, suspension reacts to every bump.

Make sure your screen border settings are correct. Go to the image settings in GT7 and make sure all you can see the border in all 4 corners. This may seem like a trivial thing but if you don't have your screen in sync with your playstation and TV it reeks havoc on the input lag and you won't be able to get full rotation with the wheel or controller.

People with the LG C1 often experience huge input lag bug when enabling original aspect ratio instead of 16:9. This is all related.

In the PS5 HDR settings make sure the hdr us set to always on. This is actually not the best setting for proper hdr but unfortunately settings this to on when supported adds a bucket load of latency.

I don't think I was able to put wide offset, just wide wheels on my widebody GT350. I don't think the game allowed. I do remember the fender rub on the car when I was setting it up. It's really obvious in VR because the wheel stops turning in front of your eyes, despite continuing to turn the wheel in your hands. I looked at mine and I am running it at 130mm front ride height, though I typically run CS on that car. I did put a set of Sports Softs on it and take it out for a few laps this evening, and while it was hilarious that you could just flatfoot it out of turns, I didn't find any fender rub or bottoming at its current height.

There were a few other cars I recall like that. The E36 prevented wide offset with a widebody as well, if I recall correctly. I guess their widebody isn't wide enough to prevent clipping.

How do the screen border and HDR settings affect lag? Ive not noticed any difference in input lag.

If that was related to my bouncy, bouncy, comment. Im in vr, so think its relevant

Maybe you couldn’t put wide offset on it, or maybe I put different rims on. I just remember finally getting that car, couldn’t do wide anything on it, bought a second, widebody it, same problem with wide stuff. Unless, you buy suspension and begin stiffening springs and jacking it up.

I just work around it, but the latest big physics change I was a bit disappointed a bone stock pantera widebodied with wide tires and offset would get fender rub. I think that was with sports soft but that car was an absolute dream that way. It’s still not bad but I think I removed offset from it now. I’m not throwing suspension on it to fix a problem that wasn’t there before.

I drove my trans am setup one as it was the only widebody one I had. I can make a new settings sheet and try it on stock suspension at some point. I don't think I've driven it with a widebody but still stock suspension. Probably not a common scenario, but I can't say I'm surprised, that like the E36 the widebody isn't quite wide enough.
